I've got a strange problem with the SD card reader on Bootcamp. It reads some of my cards fine (one 8GB, one 4GB, and one 512MB), but it has problems with some others (64GB SDXC, an identical 8GB). When I try to read a file from the 64GB one, it usually freezes the application trying to open it, or sometimes it says an unknown error occurred. If I try to write to the card, it takes forever and is almost always corrupted when reading on another computer.
This problem seems to be with the built-in card reader drivers for Bootcamp, because it works perfectly on the Mac side and also works perfectly when I use an external card reader in Bootcamp.
I've got Parallels installed to use Bootcamp without restarting, I don't know if this is affecting it... I've tried uninstalling the "Broadcom SD Host Controller" and removing drivers and reinstalling, but nothing's changed...
Just to be clear, I'm in Windows directly, not through Parallels...
Things I've tried
- Reinstalling "Broadcom SD Host Controller"
- Reinstalling WindowsSupport drivers
- Reinstalling Windows entirely
- Formatting cards as exFAT in Mac
